Patent JP-S61294699-A (JP)
Title: Cmos transistor circuit
Inventor: AIKAWA MASATOSHI
IPC: H03K19/096
Filed: 1985-06-20
Abstract: PURPOSE:To perform high-speed operation by simple constitution with low power consumption by dividing precharged signal lines into two parts, i.e. part to which a TR for a decoder is connected and other parts by using an n channel MOSTR and arranging a p channel MOSTRs at each part. CONSTITUTION:When a clock signal phi is at H, an n channel MOSTR NT1 is on and a p channel MOSTR PT3 is off, thereby outputting an output signal Vout corresponding to an address signal ADi. In a precharge period wherein the signal phi falls to L, the NT1 turns off, nodes A and A' are separated electrically, and respective signal lines are precharged by the PT1 and PT3. At this time, a node A' is separated electrically from the node A, so there is no influence of n channel MOSTRs T1-Tn upon parasitic capacity, so that signal lines are precharged at a high speed. An input to an inverter I responds to the signal phi at a high speed in combination with the effect of PT2 and the power consumption also decreases.

Title: Field effect transistor
Inventor: HOSHI MASAKATSU
IPC: H01L21/28
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To provide a field effect transistor which can be improved in drain breakdown voltage and can be manufactured through a simple process. SOLUTION: A field effect transistor has a U-gate electrode structure with U-shaped grooves 55 formed on one main surface of an N-type SiC semiconductor region 20, and gate electrodes 80 insulated by gate insulating films 70 are formed in the grooves 55. In the region 20, P-type SiC regions 60 which are faced opposite to the sidewalls of the grooves 55 are formed and channel regions are formed between the regions 60 and insulating films 70. Since the channel regions are formed outside the grooves 55, it becomes unnecessary to form the channel regions epitaxially in the sidewalls of the grooves 55 damaged by trench etching. Therefore, the channel resistance of the channel areas can be improved, by improving the quality of films and the manufacturing process of the transistor become easier.  In addition, since the voltage applied to the gate insulating films 70 is shielded by depletion layers extended from the P-type SiC regions 60, the drain breakdown voltage of the transistor can be improved.
